A disconnect-type sawtooth cutter for promoting loose small-grained output of sponge titanium cutting, including fixed block 1 and with fixed block matched with oblique sawtooth form cutting edge 2, fixed block and oblique sawtooth form cutting edge both can install on the knife rest of hydraulic press 9 jointly detachably, when the installation, fixed block 1 accessible countersunk head bolt is connected with the knife rest of hydraulic press, this connected mode has increased the resistance of vertical direction when the cutting, avoid appearing connecting not hard up problem, countersunk head bolt and the counter bore quantity that corresponds can set up to 16~32, thereby can realize depositing on the knife rest with fixed block 1 is permanent, only change oblique sawtooth form cutting edge 2 can during the change.
As shown in fig. 2, the bottom of the serrated blade 2 is disposed obliquely along the axial direction thereof, and a plurality of through grooves 5 are provided at intervals on the bottom of the serrated blade 2 so as to penetrate through the end surface thereof, and the through grooves 5 are disposed obliquely with respect to the axial direction of the serrated blade 2.
As shown in fig. 6, the upper ends of the through grooves 5 form saw-toothed upper blades 6, the lower ends form saw-toothed lower blades 7, and the upper blades and the lower blades are arranged in parallel. At the descending in-process of disconnect-type sawtooth cutter, lower cutting edge 7 contacts earlier with titanium lump 10 and plays the cutting action, can form more small-size titanium sponge through the extrusion that leads to groove 5, goes up cutting edge 6 afterwards and cuts the bold titanium sponge once more, finally sticks together the titanium and cuts into the titanium piece that the size is less, satisfy breaker pan feeding size. Compared with the existing cutting edge, the oblique sawtooth-shaped cutting edge has high forming rate, can meet the requirement of the feeding size of a crusher only by cutting once, and has the forming rate of a titanium block with the diameter less than 300mm of more than 90 percent by cutting once, which is 2 times that of the existing linear cutter.
Further, the shape of the cutting edges of the upper blade and the lower blade includes, but is not limited to, an inwardly concave groove-shaped structure formed by combining a plurality of straight lines and arcs. In order to achieve the best use effect, round transition angles are arranged between the straight lines and the circular arcs which form the groove-shaped structure and between the straight lines and the circular arcs and the oblique sawtooth-shaped cutting edge 2.
Example 1
In this embodiment, as shown in fig. 7, the shape of the cutting edge 8 is formed by combining an obliquely arranged straight line, a horizontally arranged straight line and a section of circular arc, and the three are sequentially connected through a circular transition angle and then connected to the oblique sawtooth-shaped cutting edge 2 to form an inward concave groove-shaped structure.
Example 2
The difference between this example and example 1 is that: the shape of blade is formed by the combination of two straight lines that the slope set up, and two straight lines that the slope set up are symmetrical to be set up and both connect back to oblique sawtooth form cutting edge 2 through circular transition angle, form the V type structure of handstand.
Example 3
The difference between this example and example 1 is that: the shape of the cutting edge is formed by combining a plurality of obliquely arranged straight lines, and the obliquely arranged straight lines are connected with each other through a circular transition angle and then connected to the oblique sawtooth-shaped cutting edge 2 to form an M-shaped structure.

Example 5
In this embodiment, the shapes and sizes of the cutting edges 8 of the upper blade 6 and the lower blade 7 are different, and the shapes of the cutting edges can be randomly selected in embodiments 1 to 3, and of course, a plurality of straight lines and arcs can be automatically combined to form an inward-concave groove-shaped structure according to needs.
Example 6
This example differs from example 4 in that: as shown in fig. 3, in this embodiment, an anti-wear boss 3 arranged in parallel with the end surface of the miter-saw-tooth-shaped blade is formed by extending outward the bottom side of the miter-saw-tooth-shaped blade 2, and the anti-wear boss is used to prevent the cutter from being worn and contaminating the titanium sponge during the cutting process, and in this embodiment, the anti-wear boss is arranged at the back of the miter-saw-tooth-shaped blade 2.
Example 7
In this embodiment, the size of each component is further limited to serve as a preferred embodiment for implementing the present invention, as shown in fig. 5 and 6, a protrusion is disposed on the top of the saw-tooth-shaped blade 2, the length of the protrusion is L4, a groove matched with the protrusion is disposed on one side of the fixing block 1 close to the anti-wear boss, the length of the groove is L3, and the height of the groove is L2, as shown in fig. 4, an assembly gap between the fixing block 1 and the saw-tooth-shaped blade 2 is L1, wherein L1 is 0-50 mm, L2 is 0-200 mm, and L3 is 20-800 mm. L1 is used for adjusting the laminating degree between fixed block 1 and the oblique sawtooth form cutting edge 2, and the cutter left and right sides need reserve the clearance, and the laminating between the two of being convenient for is inseparable to prevent that the cutter from causing the fracture because of the atress is inhomogeneous in the cutting process, wherein L3= L4+2L1, fillet R1 guarantees fixed block 1 and oblique sawtooth form cutting edge 2's intensity, prevents to fracture.
The lower cutting edge 7 of the oblique sawtooth-shaped cutting edge selects proper oblique sawtooth width L5, adjacent oblique sawtooth spacing L6, oblique sawtooth inclination angle theta, sawtooth cutter depth L7 and transition fillet R2, wherein L5 is 0-800 mm, L6 is 0-400 mm, L7 is 0-300 mm, inclination angle theta is 0-90 degrees, as shown in figure 7, theta is an included angle between the arrangement direction of the upper cutting edge and the arrangement direction of the through groove, the size of the theta angle determines the amount of small-granularity sponge titanium formed by breaking in the cutting process, L5 and L6 determine the width and density of the sawtooth of the cutter, and L7 determines the thickness of the cutter during cutting. Fillet R2 is 1~200mm, and the effort is concentrated when avoiding the cutting, and the cutting edge that causes bursts open or breaks.
The separated sawtooth cutter comprises a fixed block and an oblique sawtooth-shaped cutting edge matched with the fixed block, and the unique structural design of the oblique sawtooth-shaped cutting edge is combined, so that the cutter has the advantages of high cutting efficiency and long service life, and the service life of the cutter is about 2 times that of a linear cutter; the yield of small granularity of 3-12.7mm generated during cutting is improved by 3 times, and the purchasing cost of the cutter is reduced by 1 time.
